A ground water model of the Williams Lake watershed Hubbard County, Minnesota

摘要

Two-dimensional ground-water models were used to simulate groundwater flow in the Williams Lake watershed. The models were used to estimate the seepage rates to and from Williams Lake, and to determine model sensitivity to several parameters governing the flow systems. The models are based on a two-dimensional, block-centered, finite-difference scheme. A steady-state model was developed for a period in early July 1979, and this model provided initial conditions for a transient simulation through June 1981. The results of the modeling and sensitivity analysis showed that the model is most sensitive to the thickness, and hydraulic conductivity of the lake bottom sediments.
